Towards a generalized Maeda conjecture for modular forms with quadratic nebentypus

Debargha Banerjee, Dhrubajyoti Das, Srijan Das +2

We establish a lower bound for the number of non-CM Galois orbits of newforms in with non-trivial quadratic nebentypus for sufficiently large weights. Extending th…

Measurement-Induced Local Dephasing Generates Symmetrically Located Entangled Sites in a Fermionic Tight-Binding Lattice

Aitijhya Saha, Srijani Das, Debraj Rakshit

We investigate an odd-sized fermionic open tight-binding chain subjected to stochastic projective measurements at its central site, effectively inducing localized dephasing. Focusi…

A note on extensions of -adic representations of

Debargha Banerjee, Srijan Das

We compute extension groups in the category of duals of -adic Banach space representations of . Focusing on representations arising from the -adi…

Ordinary local representations and $\Ext$ groups

Debargha Banerjee, Srijan Das

We can associate an admissible unitary representation of $\GL_2(\Q_p)$ with every local Galois representation by the -adic local Langlands correspondence. If $…

Device-Independent Anonymous Communication in Quantum Networks

Srijani Das, Manasi Patra, Tuhin Paul +2

Anonymity is a fundamental cryptographic primitive that hides the identities of both senders and receivers during message transmission over a network. Classical protocols cannot pr…

Sublinear Sketches for Approximate Nearest Neighbor and Kernel Density Estimation

Ved Danait, Srijan Das, Sujoy Bhore

Approximate Nearest Neighbor (ANN) search and Approximate Kernel Density Estimation (A-KDE) are fundamental problems at the core of modern machine learning, with broad applications…
